Live API Question - Open Plug-In Edit window ?
This isn't possible via Max for Live or the Live API based on my research and Cycling '74 support said: "There's no way to implement this in the MFL LOM"
However, I'm currently trying to do it via AppleScript and the [shell] object with an osascript. Almost have it working.
I'll post the solution here if you're interested: https://cycling74.com/forums/opening-plug-in-window
Note: My solution will only work on a Mac, for now.
